As a small business owner, you're likely no stranger to the concept of PCI compliance, but you might not know where to start or what it entails. The Payment Card Industry Data Security Standard (PCI DSS) is a set of security standards designed to ensure that all companies that accept, process, store, or transmit credit card information maintain a secure environment.
The PCI DSS requires businesses to have a firewall configuration in place to protect cardholder data. This includes implementing a firewall to block incoming and outgoing traffic, and configuring the firewall to allow only necessary traffic to pass through.
Having a firewall is just the beginning, as the PCI DSS also requires businesses to implement access control measures to ensure that only authorized personnel have access to cardholder data. This includes assigning a unique ID to each user and limiting access to sensitive areas of the system.
PCI Compliance Basics
PCI compliance is a set of standards that ensures the security of cardholder data. It's a must for any business that stores, processes, or transmits cardholder data.
The Payment Card Industry Data Security Standard, or PCI DSS, is a set of baseline technical and operational requirements designed to protect payment account data. It was first formulated in 2004 by five major credit card companies.
To become PCI compliant, you'll need to go through a series of steps, including determining which system components and networks are in scope for PCI DSS, examining the compliance of system components in scope, and submitting required documentation.
The PCI requirements are grouped into six goals, with different steps to achieve each. These requirements work together to protect cardholder data, including the primary account number on the front of the card, the security code, and any Personal Identification Number (PINs) entered by the cardholder.
Here are the key terms to understand when it comes to PCI compliance:
- PCI DSS Scoping: Determining which system components and networks are in scope for PCI DSS for your business.
- Assessment: Examining the compliance of system components in scope following the testing procedures for each PCI DSS requirement.
- Reporting: The assessor or entity submits required documentation, like the Self-Assessment Questionnaire (SAQ) or Report on Compliance (ROC), including documentation of all compensating controls.
- Clarifications: The assessor or entity clarifies or updates report statements (if applicable) upon request of the acquiring bank or payment card brand.
The latest version of PCI DSS, version 4.0, was released in March 2022. It's essential to keep all validation documentation readily available to ensure you're up to standard.
Security Measures
As a business owner, securing your network and systems is crucial to prevent payment fraud. Global online payments surpassed $81 billion in 2022, providing hackers with numerous opportunities to execute payment fraud.
To build a secure network, you need to put the proper controls in place to prevent unauthorized access. This includes implementing a risk assessment to deliver full visibility into your existing security environment.
Having a comprehensive understanding of your security environment will help you identify which security patches provide the maximum protection against exploitation. This is essential to ensure your organization's security.
Implementing strong access control measures is also vital to restrict what users can see in your IT environment. Users should only be granted access to cardholder information on a need-to-know basis, based on the principle of least privilege.
Network Security
Network security is a crucial aspect of PCI compliance. You must install firewalls on your computers and internal network to protect against unauthorized access.
A firewall is usually already part of your computer's operating system, but it's essential to check that it's operating properly. This includes configuring rules and criteria for your firewalls and routers to create a standardized process to restrict inbound and outbound traffic from "untrusted sources."
To ensure your organization can continuously discover vulnerabilities, you'll need to monitor and test your networks regularly, including testing and maintaining system components, processes, and legacy, cloud-based, and third-party software. This includes tracking and monitoring all access to network resources and cardholder data, establishing a logging process to troubleshoot and investigate security incidents.
Here are some key network security measures to implement:
- Secure configuration files and synchronize them.
- Install firewalls at each internet connection and between the DMZ and internal network zone.
- Maintain a list of firewall rules with business justification for use of all services, protocols, and ports allowed.
- Implement anti-spoofing measures to detect and block forged source IP addresses.
- Segregate system components that store cardholder data from the DMZ and other untrusted networks.
Regularly Monitor and Test Networks
Regularly monitoring and testing your networks is crucial to ensure your organization can continuously discover vulnerabilities. You'll need to regularly test and maintain system components, processes, and legacy, cloud-based, and third-party software.
Monitoring and testing your networks will help you identify potential security threats before they become major issues. This includes testing firewalls, anti-virus software, and other security measures to ensure they're functioning properly.
To ensure your logs are accurate, all access to system components must have a corresponding audit trail. This will help you troubleshoot and investigate security incidents more efficiently.
Here are some key points to consider when it comes to monitoring and testing your networks:
- All critical system time clocks must retrieve time information from a single reference time source on a regular basis to ensure consistent timestamps in logs.
- Audit trails must be secured to prevent altering and must be maintained for at least one year, with a minimum of three months immediately available for analysis.
- Logs and security events must be reviewed regularly to identify anomalies or suspicious activity.
Regularly monitoring and testing your networks will help you stay one step ahead of potential security threats. By following these best practices, you can ensure your organization's network security is robust and effective.
Firewall Basics
Firewalls are a crucial part of network security, and it's essential to understand their basics. You must install firewalls on your computers and internal network to protect against unauthorized access.
Your computer's operating system likely already has a firewall as part of its security software, but it's crucial to check that it's operating properly.
A well-configured firewall can help prevent hackers from gaining access to your organization's network and systems. Global online payments have surpassed $81 billion in 2022, giving hackers more opportunities to execute payment fraud.
To configure a firewall, you should document the process so that it's clear to your IT and security teams how cardholder data flows between systems and networks. Review these configurations every six months.
Here are some key firewall management best practices:
- Configuration files must be secured and synchronized.
- Firewalls must be located at each internet connection and between any DMZ and the internal network zone.
- A list of firewall rules, including business justification for use of all services, protocols, and ports allowed must be maintained.
- Perimeter firewalls must be installed between all wireless networks and the cardholder data environment (CDE).
- Personal firewalls must be installed on any mobile or employee-owned devices that connect to the internet when outside the network and which are used to access the network.
- A DMZ must be implemented to limit inbound traffic to only system components that provide authorized publicly accessible services, protocols, and ports.
- Anti-spoofing measures must be implemented to detect and block forged source IP addresses from entering the network.
- System components that store cardholder data must be in an internal network zone, segregated from the DMZ and other untrusted networks.
- Private IP addresses and routing information must not be disclosed to unauthorized parties.
System Security
System security is crucial to prevent payment fraud and data breaches. Global online payments have surpassed $81 billion in 2022, creating more opportunities for hackers to execute payment fraud.
